1.先上传图片，然后定义一个隐藏的容器Hbox，定义一个Image组件，将上传的图片源加载到当前这个Image组件中，将Image组件添加到隐藏的容器Hbox中，监听Event.RESIZE事件，然后在获取Image的contentHeight与contentWidth即可，如果不符合你需要的宽高，再将已上传的图片删除即可。源码处理如下：
protected function upload(event:MouseEvent):void
{
URLUtils.commonUpLoadFileDir("UploadFile/view/xml/images",function(dataFileNameUpload:String,fileName:String):void{
dataFileName = dataFileNameUpload;
trace("图片上传路径:" + MyRemoteObject.idcWeb + dataFileName);
image = new Image();
image.source = MyRemoteObject.idcWeb + dataFileName;
image.visible = false;
test.removeAllElements();
test.addElement(image);
image.addEventListener(Event.RESIZE,onResize);
trace("宽：" + image.width + ",高：" + image.height);
},imagesFilterArray);
}
private function onResize(event:Event):void{
if(image.contentHeight == 716 && image.contentWidth == 712){
iconId.text = dataFileName;
cloudIndInfo.imagePath[0] = dataFileName;
}else{
//服务端删除文件
ResourceManagerService.getInstance().deleteImage(dataFileName,function(result:Boolean){
if(result){
iconId.text = ‘‘;
cloudIndInfo.imagePath[0] = ‘‘;
Alert.show("请上传高度为716，宽度为 712的图片。");
}
})
}
trace("高度：" + image.contentHeight);
trace("宽度：" + image.contentWidth);
}
